秤。A weight detector that detects the weight of the item, an A/D converter that converts the analog weight data detected by the weight detection section into a digital amount, and the output of the A/D converter is stored in the zero point storage section. A subtraction unit that subtracts the output of the A/D converter when no load is applied, a reference value storage unit that stores a reference value corresponding to the reference weight for calibration, and a subtraction unit that subtracts the output of the A/D converter when the reference weight for calibration is measured. From the output of the unit and the level value stored in the reference value storage unit,
A weight calculation unit that calculates a weight, a weight storage unit that stores the weight calculated by the weight calculation unit, and a weight calculation unit that calculates a measured value from the output of the subtraction unit and the weight stored in the weight storage unit. The electronic scale has a span correction switch that is operated when adjusting the span, a stability determination section that checks the output of the A/D converter to detect stationary stability during weighing, and a balance that loads a reference weight onto the weight detection section. a vertical movement mechanism for removing;
When the span correction switch is operated, the A/D converter output is stored in the zero point storage section, and then the vertical movement mechanism is controlled.
An electronic scale comprising: a control section that loads a weight of a reference weight onto a weight detection section, and further issues a calculation command to a weight calculation section when the stability determination section detects static stability.
